Can i you the relay below to turn or or off heavy appliances like geyser and air conditioners?
This is the link :
If not can someone suggest a relay available in market that i can use?
check what's your appliance requirements. 2A seems very low for an AC unit (Depending on the BTU capacity amp requirements can easily range from 15 to 45 amps)
Do you think this will work?
i don't know. what are the requirements of the load?
seems you don't know enough to play with high current. That can kill you, burn your house down, void your insurance etc... you should seek advice from a local professional
Neither of those will do the job !
Find the current rating of the device you want to switch and select on that basis . Really it’s probably not a good idea for you to be doing this with mains electric if you can’t answer yourself -Sorry .
That is a cheap hobby style relay, not likely to have a long life. You need something intended for the job.
those relays are much too large for an air conditioner.
for an air conditioner, you only need to open the control wire and NOT the mains power
For the pump/geiser, check the nameplate.
up to about 1/3 HP they get power turned off, but over that, you must use a contactor.
a manual contactor will have mechanical buttons you need to move with some pressure
a larger motor will have a Motor Starter and that too, will have low current control wire
we cannot know what you have, you need to look at the devices.
EVERY time you need to connect to or control mains power, you need to get a licensed electrician to look at the parts. NOT an internet forum.
